I .My invention relates to a newspaper stuffing machine,-by which is'meanta machine for assembling or stufling newspapers. I a

- .Qne of theobjects of the invention is to provide a practical and advantageous ma chine for the'purpose.

Another object of theinvention is .to secu're efficiency, effectiveness and speed in machines of this character.

'Another object-of the invention isto avoid crumpling the-papers or sections in the stufiing process, to prevent j ams andclogging the machine and so interferingwith'or stopping the wholeprocess. Another object of the invention is topermit the" effective handling of paper sections of "various kinds of paper, thin, medium, filmy, thick and so on, and particularly to prevent trouble when thin and filmy paper is used;

Another object of the invention is to provide a simple, advantageous and effective mechanism for inserting one or more inner or insert sections of the newspaper,into an outer or cover section.

Other ob ects of the invention are tosecure the foregoing and other. useful ends in a simple and expeditious manner.

In thedrawings.:- g V Fig. lis a side view of part ofa stufling machine with certain partsin section.

' Fig. 2 is a section at the line 2-2 of Fig. 1.

Fig. 3 is a plan of aportion of-the conveyor Fig. 5 isa longitudinal sectionshowing the carrier frame and its operating mechanism.

Fig. 6 is a section at theline 66 of Fig.3. Figs. 7 8 and 9 are details showing the feeder arm and the trackerbar in various positions.

The drawings show the stufiing mechanism whichis the particular subject of this .in-

vention, as applied to a stuffing machine arranged to handle a multiplicity of sections of newspapers, such as, for instance, the ad.

section, the editorial section, the fashion, sports andcover sections, or as many as there happen to be in any particular publication to be handled by the machine.

tion in the connecting arm 33 which oper- Fig. 1 shows what may be termed a magacaused to deposit their contents on a conveyor bed indicated at 16, and propelled orconveyed toward the cover-section magazine by the conveyor chain 17 which has the tappets 18. 1

It now having been explained that the insert sections are brought to the locality ofthe cover sections, the operation of the c0ver-section magazine will bedescribed in general. Thesupport 14 is stationary. The support 15 which movable and, pivoted at 20, is caused to retract bythe action-ofcams (not shown) mounted on the shaft 21. Thepaper section is gripped between a roller 22 and a segment 23 and then carried along thereby in the path determined by the guide 24, then entering between the rollers 25 and 26 from and by which it is conveyedto the attrition segments 27 and 28 on the shafts 29 and 30. Atthis point the cover section is heldin an open position'by mechanism not shown in this application because it constitutes no part r of the present invention. The shaft .29 is interconnected to the shaft 17 of the conveyor '17, andalso to the shaft 30 in any convenient manner (not shown) and is driven by any available source of power (not shown). The shaft 29 has mounted at one end thereof a short crank arm'31 having a wristpin 32 arranged to translate the rotary motion of the shaft 29 to reciprocating'moates, through the bell crank 34, the connecting rod 35. This rod is attached at 36 to a short arm 37 for operating the shaft 38 which is mounted for rocking in journals 38' -38 which are supported on the main;

frame of the machine. This motion is transmitt-ed and multiplied to and by the long lever 39 for operating the feeder devices. The arm 39 has, connected at 40, the rod 41 which carries a spur pinion 42 journalledon the shaft 43; this shaft 43 is fixed in the members 44-44 of the forked rod-head 45. The pinion 42 is arranged to mesh With a stationary rack 46 and a movable rack 47. To insure the proper relation of the teeth of the rack 46 and the pinion 42, the guide rollers 4949 are provided whose diameters are equal to the diameter of the pitch circle of the pinion 42 and which roll on guide rails 5050. placed on a level with the pitch line of the teeth in the rack 46. The rollers and pinion are preferably fastened together as by rivets 51 to rotate as one unit.

A pedestal 52 supports the tracks 5050, the rack 46 and also the U-shaped brackets 5252 These brackets 52 also furnish supports forthe guide members 5353 which have tongue and groove engagements at 54 and 55, the grooves 55 being in the sides of the rack 47. The members 53 are secured by bolts 53 to the brackets 52*.

The rack 47 has secured to it the frame A, which is composed of the cross bars and 61 which are secured to the rack 47 for move ment therewith at 6262 and longitudinal members 63-63 which are guided on either side of the members 5353. Outside rails 64-64 extending parallel with the members 63-+63 are also carried by the cross pieces 60 and 61, the members 6464 are provided with stationary tracks 6565. The members 63, 64 and65 are preferably made of rectangular stock bars, so called, as they afford finished surfaces and insure a light and smoothly moving device.

Carried by the frame A are the feeder arms 7O pivoted at 717l' to 'either'si'de of this frame. As the frame reciprocates for feeding or stuifing the inserts into the cover sections, these arms are caused to ride on the tracker bars 7 2 pivoted at 73 to the stationary frame, which is supported by the member 52. The feeder arms 70' each has a roller 74, and the tracker bars-72 are located in the path of these rollers and the bent or curved ends 7 5 cause the rollers, asthey approach, to climb the tracker bar, thus raising the feeder arm above the general plane of the conveyor bed and the forked forward ends 76 of these arms engage the rear'edge of the insert sectlons and propel them forward, toward and into the cover sections.

The timing of thesearms by virtue of the rack and pinion drive arrangement just described, is such thatthey carry the paper sections at agreater speed than the tappets 18 on the conveyor chains 17, and the timing as to speed and moment of action is such that the paper sections are carried forward, clear of these tappets before tnev round tne curve of the sprocket 17 of the shaft 17 In Fig. 7 is shown the roller 74 approaching the curved portion 7 5 of the tracker bar 72; its direction of travel is indicated by the arrow B. l

' er in the position indicated in Fig. 8 at "('4 and is then in a plane below that occupied by the next oncoming insert section. con tinued travel brings the roller underneath the tracker bar and since this bar is pivoted as at 7 3, it-isfree to swing up when the roller contacts the part 75. The frame A further retracts and brings the roller entirely clear of the tracker bar-and is then ready for the next excursion. The arm 70 has the end thereof chamfered at 70 to limit its movement about its pivotal point.

- The cross bar 61, is beveled along the edg 61, to prevent the frame from injuriously contacting the edge of the next oncoming insert; it will be understood that the papers, carried by the conveyor tappets 18 and the frame A, retracting to initial position are travelling with respect to each other, at a relatively high speed and necessarily so, since the frame must return the arms 7 O to their extreme retracted position while the papers continue to advance in an opposite direction, until the arms 70 arrive at a position just rearward of the paper insert sections which are to be acted upon as previously described.

It will be understood that changes and modifications may be made'without departing from the spirit of the invention.
